49FCT806ASOG

Overview

The Renesas Electronics Corporation 49FCT806ASOG is a Fast CMOS inverting buffer and clock driver. It utilizes 0.5-micron CMOS technology to provide two independent output banks, each driving five buffers from a standard TTL-compatible input. The device features rail-to-rail output swing, low capacitance inputs with hysteresis, and a dedicated monitor output for diagnostics. It operates within a commercial temperature range of 0°C to +70°C at VCC = 5V ± 5%. Key electrical parameters include a maximum propagation delay of 5.3 ns, guaranteed low skew under 700 ps, and high drive capability of -24mA IOH and +64mA IOL.

Feature Summary

• Two independent 1:5 fanout output banks with active LOW 3-state control
• Guaranteed low output skew less than 700 ps (max.)
• TTL compatible inputs and outputs with rail-to-rail voltage swing
• Integrated 'heartbeat' monitor output identical to other outputs

Applications

• Clock distribution networks requiring low skew
• PLL driving applications utilizing the monitor output
• High-speed digital systems needing TTL/CMOS interface compatibility

Procurement Notes

Verify component authenticity through authorized channels. Confirm package type matches SOIC specifications. Check date codes regarding pin 8 internal connectivity variations. Ensure compliance with RoHS requirements as non-green parts have reached end-of-life status.

Selection Notes

Select this model for designs requiring an inverting clock driver with dual independent banks. Verify that the commercial temperature range (0°C to +70°C) meets system environmental needs. Ensure load capacitance does not exceed 50 pF to maintain specified switching characteristics.

Part Context

This component belongs to the FCT series of Fast CMOS logic devices manufactured by Integrated Device Technology, now part of Renesas Electronics. It serves as a specialized clock driver designed for high-speed signal integrity in complex digital architectures.

Replacement Considerations

IDT49FCT806AEB is a similar inverting clock driver offering comparable functionality. Verify pin compatibility and electrical specifications before substitution.
